Indentation damage detection in thermoplastic composite laminates by using embedded optical fibers
(Soc. for the Advancement of Material and Process Engineering, 2005)
In recent years, optical fibers have received attention as sensors for the purpose of in-service health monitoring in composite materials. Advantages of optical fiber sensors over conventional sensing methods are well-known ...
Evaluation of the fourier transform of e(-ux2) for imaginary U
(Springer Science and Business Media Deutschland GmbH, 2006)
It is shown that the Fourier integral of the function exp(-ux(2)) exists not only for u satisfying Re u gt 0 but also for u that satisfies Re u >= 0. The proof is given by evaluating this integral for imaginary u.
Evolution of the wave function of an atom hit by a photon in a three-grating interferometer
(Physica Scripta, 2009)
In 1995, Chapman et al (1995 Phys. Rev. Lett. 75 2783) showed experimentally that the interference contrast in a three-grating atom interferometer does not vanish in the presence of scattering events with photons, as ...
Electromagnetic energy flow lines as possible paths of photons
(Physica Scripta, 2009)
Motivated by recent experiments where interference patterns behind a grating are obtained by accumulating single photon events, we provide here an electromagnetic energy flow-line description to explain the emergence of ...
Subtle inconsistencies in the straightforward definition of the logarithmic function of annihilation and creation operators and a way to avoid them
(Journal of Physics A-Mathematical and Theoretical, 2009)
Using the resolution of identity spanned by coherent states of the harmonic oscillator, any entire function of the creation and the annihilation operators and its action on a vector in Hilbert space can be defined directly ...
The resultant of non-commutative polynomials
(Društvo matematičara Srbije, Beograd, 2008)
Let R = K[x; σ] be a skew polynomial ring over a division ring K. Necessary and sufficient condition under which common right factor of two skew polynomials exists is established. It is shown that the existence of common ...
Mode Analysis of the Optical and the Microwave Waveguides Using Electromagnetic Energy Flow Lines
(Acta Physica Polonica A, 2009)
To better elucidate the essential energy transmission Mechanism in the most common, typical waveguides, the electromagnetic energy flow lines for a planar optical slab waveguide and a microwave rectangular waveguide are ...
DRM formulation for axisymmetric laser-material interactions
(WIT Transactions on modelling and simulation, 2006)
The modeling of laser-material interaction using the boundary element dual reciprocity method (BE-DRM) is presented. Thermal effects in the case of cylindrical geometry for mono as well as multi layer structures were ...
The influence of concentration of Nd-Fe-B powder in composite coating of optical fiber to the sensibility to external magnetic field
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2005)
Multi-mode optical fiber with magnetic composite coating was investigated as an optical fiber sensor element (OFMSE) for magnetic field sensing The composite coating was formed with dispersions of permanent magnet powder ...
Univalence and starlikeness of nonlinear transform of certain class of analytic functions
(Proceedings of the Indian Academy of Sciences, 2009)
